Is cellular respiration anabolic or catabolic process

Sir, the term “literacy” means something different in each discipline taught in schools. Scientific literacy does not just mean “being able to read, write, and communicate”; it means “being able to read, write, and communicate–like a scientist”. Sarah took a big step by posting this comment. The attention she has paid to what you wrote is evidence that she is in the process of constructing meaning about the subject matter. As her scientific literacy improves, her learning improves—the two feed off of one another.
I must ask, if you meant something different (it’s not coming from thin air), then why did you write it the way you did? In my opinion, you owe her more than a flippant reply.
Cool dog by the way.
Respectfully (and proud as hell of my student), Geoff

Electron transport in aerobic respiration requires oxygen directly. The electron transport chain is a series of protein complexes and electron carrier molecules found within the mitochondrial membrane in eukaryotic cells. Through a series of reactions, the "high energy" electrons generated in the citric acid cycle are passed to oxygen. In the process, a chemical and electrical gradient is formed across the inner mitochondrial membrane as hydrogen ions (H+) are pumped out of the mitochondrial matrix and into the inner membrane space.

The first step in cellular respiration in all living cells is glycolysis , which can take place without the presence of molecular oxygen. If oxygen is present in the cell, then the cell can subsequently take advantage of aerobic respiration via the TCA cycle to produce much more usable energy in the form of ATP than any anaerobic pathway. Nevertheless, the anaerobic pathways are important and are the sole source of ATP for many anaerobic bacteria. Eukaryotic cells also resort to anaerobic pathways if their oxygen supply is low. For example, when muscle cells are working very hard and exhaust their oxygen supply, they utilize the anaerobic pathway to lactic acid to continue to provide ATP for cell function.
